SAMUEL S. FRETZ, OF PHILADELPHIA, PENNSYLVANIA.

UMBRELLA-RUNNER.

SEECIFICATION forming part of Letters Patent N 0. 681,635, dated August 27, 1901. Application filed August 4, 1900. Serial No. 25,885 (No model.)

To all whom, it may concern:

Be it known that I, SAMUEL S. FRETZ, a citizen of the United States, and a resident of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Umbrella-Runners, of which the following is a clear, full, and sufficient specification, reference being had to the drawings annexed.

Prior to my invention the barrel and notch of umbrella runners had been secured together in various ways. The prevailing way, especially with the seamless-tubing-barrel runners with cut-through notches, had been that known as sweating, the notch being pushed over the runner-barrel and a little solder being made under the blowpipe to flow around the joint between them and into the space between them. This process was slow, comparatively expensive, and not entirely satisfactory in other respects, especially because it was apt to deface somewhat the barrel, and the joint between the barrel and the notch was not always reliable and the two parts sometimes separated. It was, however, the accepted way of securing the runner-notch to the runner-barrel, especially in the case of brass runners, which were used in all first-class umbrellas.

My invention has forits object,among other things, a runner that has the notch and barrel always firmly and reliably secured together, which can be produced very cheaply, and does not need any extra finishing both to unite the runner and the barrel firmly and to run no chance of disfiguring either of them. It is particularly applicable to brass runners,

which were hitherto generally made of a brass drawn-tube barrel and a notch sweated together, as above described.

Describing now my invention in detail, Figure 1 is a vertical section on the line 0; w of Fig. 2. Fig. 2 is a plan View of the runner, and Fig. 3 is a side elevation of the runner.

The barrel 0 is made in the usual manner, usually out of a drawn tube or cup,'drawn down to the required length and diameter, and the notch 13 is made of a convenient or usual construction, the inside hole thereof being made smooth (preferably by turning or boring) and small enough in diameter to fit closely the outside of the runner-barrel C, so that it is with difficulty forced over the same. To unite the two parts together, I place tho notch onto the runner-barrel O, raising a slight shoulder on the barrel Where the bottom of the notch rests when in its position on the completed runner. I can do this either by slightly depressing the barrel where the notch rests or by driving up or stripping the metal along the barrel, or by both, or by other suitable manner raise a slight shoulder 3 upon the runnerbarrel, and I then proceed to spread the top of the barrel into the slots of the notch, and generally at the same time slightly spread the notch and the barrel at the top. By these means the upper end of the runner-barrel at a is made to take the form, substantially, of a frustum of a cone, the wider part of the cone being toward the end of the runner, and the sprocket b of the notch, through which the slots extend, is also spread into a conical shape, fitting against the outside of the runner-barrel. The runner-barrel, to secure the best appearance to the runner, need not extend beyond the end of the notch and may not extend quite that far. By thus spreading out the top of the notch and the top of the runner-barrel the notch is held in place between the shoulder on the runner and the expanded portion thereof, substantially as by a dovetail joint and great firmness in the connection between the two parts assured, the long substantially comically-shaped end portion Ct forming practically a circular dovetail joint.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-- An umbrella-runner consisting of a runnerbarrel provided with an outwardly-flaring substantially cone-shaped portion, at the end thereof at which the notch is applied, and a shoulder on said barrel where the inner end of the notch rests, in combination with a notch, the sprocket portion of which is provided with slots extending through the walls of said notch, the sprocketsegments of which are inclined outward, the said end portion of' the notch beingformed into, substantially,the shape of a cone, corresponding substantially with the contour of the runner-barrel; sub- 5 stantially as described.

Having now described my invention, what I claim and desire to secure by Letters Patent is as above, in token of which I have here unto set my signature this 3d day of August, 1900.
